What can contamination of reagents leads to? Unreliable results Reliable results Reproducible results Good results Catalase is the enzyme found in potatoes and It decomposes hydrogen peroxide (H202) to form water and oxygen gas. H202 + catalase - ----> H2O + 02 +E. The reaction is maintained at temperature 40 degree Celsius and there was a formation of bubbles. Based on the enzymatic reaction given, What do you think is the substance responsible for the formation of bubbles? Oxygen gas Hydrogen gas no reaction, because the enzyme catalase will be deactivated no reaction, because the enzyme catalase will be denatured Other: Based on the Fehling's test video, do you think the sugars ribose (in RNA) and the deoxyribose (in DNA) will both form a positive result (red precipitate) No Yes

1. Determine the concentration of each component (C2) in the final mixture for each run (refer to Table 4-1) for the total volume (V2) of the mixture, and the initial concentration (C1) and volume (V1) of each component). C1V1 = C2V2 2. Calculate for the reaction rate per run using the concentration of iodine and time elapsed. reaction rate = [I2] in the final mixture/time elapsed 3. Determine the reaction order with respect to l2. Also determine the reaction order with respect to C3H6O and the reaction order with respect to HCI. Round off your answers to the nearest whole number. 4. Calculate for the rate constant for each run using the reaction orders obtained (use rounded off values of reaction orders). 5. Take the average of the rate constants. 6. Determine the rate law of the reaction.

PERTINENT CALCULATIONS Remember: rate = k[C25H30CIN3]"[OH_]" where n =0 since excess OH was used. n3= 1.
